Keep in mind that using enanthate this way will cause a significant build up of testosterone in the bloodstream that will not cease to increase until four or five weeks of injections. This is due to the fact that taking a four hundred milligram injection, and another four days later, still has at least 200mg working from the previous dose. The third injection then adds another four hundred and the first is still not entirely used up. You may realistically have over a gram or so in the bloodstream before you know it. Just be careful, and keep this in mind when figuring out your dosages.
There is no set time frame of use for this compound. Regardless of your Testosterone Enanthate doses, this compound can be used for indefinite periods of time. For the TRT patient, it will be used continuously and non-stop as discontinuing use would return the individual to a low testosterone state. For the performance athlete, full cycles will normally last from 8-12 weeks with 16 weeks not being too uncommon. At this stage, most will want to come off and enter into a Post Cycle Therapy (PCT) stage. For the more advance users who live and follow a very hardcore lifestyle, they may simply lower the dose to a TRT level in a bridge phase. However, this type of use presents a lot of risk and cannot be recommended to most. As for stacking, Testosterone Enanthate stacks well with all anabolic steroids.
